    Subject[PATCH v10 0/7] cpufreq:boost: CPU Boost mode support
    This patch series introduces support for CPU overclocking technique
    called Boost.

    It is a follow up of a LAB governor proposal. Boost is a LAB component:

    Boost unifies hardware based solution (e.g. Intel Nehalem) with
    software oriented one (like the one done at Exynos).
    For this reason cpufreq/freq_table code has been reorganized to include
    common code.

    Important design decisions:
    - Boost related code is compiled-in unconditionally to cpufreq core and
    disabled by default. The cpufreq_driver is responsibile for setting
    boost_supported flag and providing set_boost callback(if HW support
    is needed). For software managed boost, special Kconfig flag -
    CONFIG_CPU_FREQ_BOOST_SW has been defined. It will be selected only
    when a target platform has thermal framework properly configured.

    - struct cpufreq_driver has been extended with boost related fields:
    -- boost_supported - when driver supports boosting
    -- boost_enabled - boost state
    -- set_boost - callback to function, which is necessary to
    enable/disable boost

    - Boost sysfs attribute (/sys/devices/system/cpu/cpufreq/boost) is visible
    _only_ when cpufreq driver supports Boost.

    - No special spin_lock for Boost was created. The one from cpufreq core
    was reused.

    - The Boost code doesn't rely on any policy. When boost state is changed,
    then the policy list is iterated and proper adjustements are done.

    - To improve safety level, the thermal framework is also extended to disable
    software boosting, when thermal trip point is reached. After cooling down
    the boost can be enabled again. This emulates behaviour similar to HW
    managed boost (like x86)

    Tested at HW:
    Exynos 4412 3.12-rc7 Linux
    Intel Core i7-3770 3.12-rc7 Linux
